Gundam

Gundam.... is big. The mecha are big, the franchise is big, and now thanks to the huge success of Gundam Wing on the Cartoon Network's Toonami programming block, Gundam is poised to take over the US. Gundam started in 1979, surprisingly during the series first run it wasn't really that successful and was canned. Then it aired in reruns for awhile till it was compressed into movie format with some new footage and became a hit.
